SPI command black-/ignorelisting for the flash chip emulator in the dummy programmer
Usage: flashrom -p dummy:spi_blacklist=commandlist flashrom -p dummy:spi_ignorelist=commandlist If commandlist is 0302, flashrom will refuse (blacklist) or ignore (ignorelist) command 0x03 (READ) and command 0x02 (WRITE). The commandlist can be up to 512 bytes (256 commands) long. Specifying flash chip emulation is a good idea to get useful results. Very useful for testing corner cases if you don't own a locked down Intel chipset and want to simulate such a thing. Example usage: dd if=/dev/zeros bs=1024k count=4 of=dummy_simulator.rom dd if=/dev/urandom bs=1024k count=4 of=randomimage.rom flashrom -p dummy:emulate=SST25VF032B,image=dummy_simulator.rom,\ spi_blacklist=20,spi_ignorelist=52 -w randomimage.rom -V Corresponding to flashrom svn r1490.
